A pulse oximeter is a medical device that indirectly measures the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmograph.. This portable, battery-operated pulse oximeter also displays the heart rate.

Why is pulse oximetry so important?

Once a patient starts losing oxygen, a doctor has less than three minutes to prevent risk of brain damage, heart failure and death.

A healthy body should never fall below 95% oxygen saturation, and oximeters can detect changes as small as 1%. Before oximeters were invented, experienced clinicians would only notice signs of hypoxia (oxygen starvation) when patients became cynaosed – literally their skin began turning blue, with oxygen saturation damagingly low at 85%.
